Matthew Robinson et. al assessed the effects of three difference exercise modalities—High Intensity Interval Training, Resistance Training, and Combination Training—in young and older adults. While all enhanced insulin sensitivity, only HIIT and combined training improved aerobic capacity, associated with enhanced translation of mitochondrial proteins. HIIT effectively improved cardio-metabolic health parameters in aging adults into their 70s. The biggest response was among older adults who participated in HIIT; among the older adults, almost 400 genes improved function following three months of training.
